PolishLinux site takes a look at KDE 4.2 based on the latest subversion branch and concludes: "As it can be seen, the KDE4 development is running at full throttle. KDE4.2 will include much enhanced functionality and versatility than KDE 4.1, but still a lot of work has to be done in many areas, especially when it comes to the stability of the applications." Hopefully some of the long standing stability and maturity issues with KDE 4.x branch are resolved before the GA release.
